Abstract (en)
[origin: WO8102172A1] Method and system for dispersing a plurality of closely associated filaments (2) so that the dispersed filaments (2a) are capable of being deposited, in a random, convoluted pattern, on a moving web-forming surface (3) to form a high machine-direction strength non-woven product (4). The filaments are preferably dispersed by impinging same against a fluid-dynamically-assisted, contoured deflection means, preferably comprising a curved, downwardly inclined deflection element (21) which is continuously traversed, generally codirectional with the filament flow, by a stream of air (50).
